"Pink Noise" Better Than "White Noise" for Sleep

Pink noise has a deeper sound than white noise; it's similar to the sounds that waterfall makes. Older people exposed to pink noise at night remembered almost 70% percent more words in a memory recall test than people not exposed to it.

A new study conducted by Northwestern University has indicated that pink noise—soft, random sound stimulation—may improve memory recall and the quality of deep sleep.

The study, which involved thirteen people aged 60 and older, has produced some promising results for those looking to slow down age-related memory loss. Subjects who were exposed to pink noise in their sleep demonstrated three times better memory recall the next day than those exposed to a sound placebo.

YouTube, Spotify, and SoundCloud are all great places to find pink noise you can play gently in the background while you sleep. Just create your own playlist, turn it on each night, and wait to see whether or not your sleep health seems to improve.

You can also download an app specifically for helpful sleep sounds, such as Relax Melodies or Noisli. Even the act of falling asleep can be easier with pink noise playing, so give it a go and see how you might benefit.
